A classic Late Frasnian chondrichthyan assemblage from southern Belgium
- Samples from the Upper Frasnian (Devonian) of Lompret Quarry and Nismes railway section in Dinant Synclinorium, southern Belgium, yielded several chondrichthyan teeth and scales. The teeth belong to three genera: Phoebodus, Cladodoides and Protacrodus. The comparison with selected Late Frasnian chondrichthyan assemblages from the seas between Laurussia and Gondwana revealed substantial local differences of taxonomic composition due to palaeoenvironmental conditions, such as depth, distance to submarine platforms, oxygenation of water, and possibly also temperature. The assemblage from Belgium, with its high frequency of phoebodonts, is the most similar to that from the Ryauzyak section, South Urals, Russia, and the Horse Spring section, Canning Basin, Australia.

Constraining the oceanic uptake and fluxes of greenhouse gases by building an ocean network of certified stations: The ocean component of the Integrated Carbon Observation System, ICOS-Oceans
- The European Research Infrastructure Consortium ?Integrated Carbon Observation System? (ICOS) aims at delivering high quality greenhouse gas (GHG) observations and derived data products (e.g., regional GHG-flux maps) for constraining the GHG balance on a European level, on a sustained long-term basis. The marine domain (ICOS-Oceans) currently consists of 11 Ship of Opportunity lines (SOOP ? Ship of Opportunity Program) and 10 Fixed Ocean Stations (FOSs) spread across European waters, including the North Atlantic and Arctic Oceans and the Barents, North, Baltic, and Mediterranean Seas. The stations operate in a harmonized and standardized way based on communityproven protocols and methods for ocean GHG observations, improving operational conformity as well as quality control and assurance of the data. This enables the network to focus on long term research into the marine carbon cycle and the anthropogenic carbon sink, while preparing the network to include other GHG fluxes. ICOS data are processed on a near real-time basis and will be published on the ICOS Carbon Portal (CP), allowing monthly estimates of CO2 air-sea exchange to be quantified for European waters. ICOS establishes transparent operational data management routines following the FAIR (Findable, Accessible, Interoperable, and Reusable) guiding principles allowing amongst others reproducibility, interoperability, and traceability. The ICOSOceans network is actively integrating with the atmospheric (e.g., improved atmospheric measurements onboard SOOP lines) and ecosystem (e.g., oceanic direct gas flux measurements) domains of ICOS, and utilizes techniques developed by the ICOS Central Facilities and the CP. There is a strong interaction with the international ocean carbon cycle community to enhance interoperability and harmonize data flow. The future vision of ICOS-Oceans includes ship-based ocean survey sections to obtain a threedimensional understanding of marine carbon cycle processes and optimize the existing network design.

Canyons of the Eastern Shore of Southern Baikal: Morphology and Genesis
- We present new data on canyons and other morphological features of the underwater slope on the eastern coast of the southern basin of Lake Baikal obtained during high-resolution bathymetric surveys of the bottom using multibeam echo-sounders ELAC SeaBeam 1050 and Kongsberg EM710S. Based on the array of bathymetric data generated, we have constructed a digital elevation model for which we used at once several software products responsible for individual tasks. Analysis of the digital elevation model has indicated that tectonic processes played the leading role in the creation of the main, most noticeable forms of relief on the underwater slope. These processes formed a graben-like depression to the south of the Posol’skaya Bank and tectogenic scarps at the foot of the southern slope of the depression as well as canyon-shaped valleys along the entire coast. We have determined that the unusual direction of the Posol’skii canyon across the coastal slope and the relatively small size of the fan in this canyon are due to the history of the tectonic development of this part of the shoreline: in the past, the canyon valley skirted the continental slope of the Selenga river paleodelta from the southeast, and after the formation of a younger graben-like depression it preserved the old direction of its channel. We have suggested that underwater erosion processes initiated tectonic lowering of the floor of the basin. Ultimately, this resulted in the destruction and erosion of the ancient geomorphological surfaces and formation of the ridge and hollow relief and canyon valleys that are currently at different stages of development. Landslide forms resulting from paleoseismic dislocations play a secondary, yet a significant role in the relief of the slope, which undoubtedly complicated the geomorphological surface. It is assumed that the fans created by the activities of the canyons, the ancient channels of canyons and landslide bodies may be promising for the search for hydrate-bearing structures in this part of the lake.

New fossils from Tadkeshwar Mine (Gujarat, India) increase primate diversity from the early Eocene Cambay Shale
- Several new fossil specimens from the Cambay Shale Formation at Tadkeshwar Lignite Mine in Gujarat document the presence of two previously unknown early Eocene primate species from India. A new species of Asiadapis is named based on a jaw fragment preserving premolars similar in morphology to those of A. cambayensis but substantially larger. Also described is an exceptionally preserved edentulous dentary (designated cf. Asiadapis, unnamed sp. nov.) that is slightly larger and much more robust than previously known Cambay Shale primates. Its anatomy most closely resembles that of Eocene adapoids, and the dental formula is the same as in A. cambayensis. A femur and calcaneus are tentatively allocated to the same taxon. Although the dentition is unknown, exquisite preservation of the dentary of cf. Asiadapis sp. nov. enables an assessment of masticatory musculature, function, and gape adaptations, as well as comparison with an equally well-preserved dentary of the asiadapid Marcgodinotius indicus, also from Tadkeshwar. The new M. indicus specimen shows significant gape adaptations but was probably capable of only weak bite force, whereas cf. Asiadapis sp. nov. probably used relatively smaller gapes but could generate relatively greater bite forces.

Mastication and enamel microstructure in Cambaytherium, a perissodactyl‑like ungulate from the early Eocene of India
- The dentition of Cambaytherium was investigated in terms of dental wear, tooth replacement and enamel microstructure. The postcanine tooth row shows a significant wear gradient, with flattened premolars and anterior molars at a time when the last molars are only little worn. This wear gradient, which is more intensive in Cambaytherium thewissi than in Cambaytherium gracilis, and the resulting flattened occlusal surfaces, may indicate a preference for a durophagous diet. The tooth replacement (known only in C. thewissi) shows an early eruption of the permanent premolars. They are in function before the third molars are fully erupted. During the dominant phase I of the chewing cycle the jaw movement is very steep, almost orthal, with a slight mesiolingual direction and changes into a horizontal movement during phase II. The enamel microstructure shows Hunter-Schreger-bands (HSB) in the inner zone of the enamel. In some teeth the transverse orientation of the HSB is modified into a zig-zag pattern, possibly an additional indicator of a durophagous diet.
